RCC Test Section
**************************************************************************
NOTE: See the materials engineer for information
for filling in the blanks.
**************************************************************************
Prior to placement of any RCC, the Contractor shall construct a test
section. The purpose of the test section is to demonstrate the suitability
of the Contractor's equipment, methods, and personnel. The test section
shall be at least [5] [_____] lifts in height and be at least [60] [_____]
m [200] [_____] feet long and [12] [_____] m [40] [_____] feet wide at the
top. The site of the test section shall be approved. After evaluation and
assessment of the test section by the Contracting Officer, the Contractor
shall dispose of the test section in an approved manner. Under no
circumstances shall the test section be incorporated into or become a part
of the permanent RCC structure. The test section shall demonstrate
sustained plant production rates, and batching, mixing, transporting,
spreading, and compaction procedures. It shall also demonstrate the
vertical face construction method along one side, the sloped face
construction method along another side, procedures for foundation and
concrete surface preparation and cleanup, procedures for placement of
bedding concrete, bedding mortar, and other conventional concrete, and the
installation of any contraction joints and waterstops. The Contractor
shall not begin RCC operations for the main structure until testing and
evaluations by the Government have been completed, and it has been
demonstrated to the satisfaction of the Contracting Officer that all
specification requirements were met. Following completion of test section
construction, [10] [_____] calendar days shall be allowed for testing and
evaluations. If the Contractor does not meet requirements as specified, an
additional test section or sections shall be constructed at no additional
cost to the Government. The date of the test section construction shall be
provided at least 7 days in advance.

3.2.5.1
Cold-Weather Placement
In Cold-weather placement the RCC shall not be placed when the ambient air
temperature drops below 0 degrees C 32 degrees F. If the ambient air
temperature does drop below 0 degrees C 32 degrees F, the surface of any
recently placed (within the previous 72 hours) and exposed horizontal RCC
surface shall not remain exposed for more than 4 hours. Surfaces that will
be exposed for longer times shall be protected as specified in paragraph
COLD-WEATHER PROTECTION as a measure to maintain RCC temperatures above 0
